Subject: Launder seed generation through rand() to ensure seed diversity.
X-Git-Tag: seed~3
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=refs%2Fmerge-requests%2F25%2Fhead;p=open-adventure.git

Launder seed generation through rand() to ensure seed diversity.

This doesn't affect reproducibility because a) the seed value written to logs is the output of this process, and b) the argument to the seed command *doesn't* get laundered.
